Creator Tools
Free browser tools that fix subtitle chores: convert, shift, merge, and check subtitles without uploading files.

What it does
Creator Tools is a set of six small, free tools for video creators, all running in the visitor's browser. It converts SRT to WebVTT, shifts subtitle timing, formats YouTube chapters, repairs garbled subtitles saved in encodings such as GBK and Shift-JIS, merges two subtitle files into bilingual subtitles by time overlap, and checks Chinese, Japanese and Korean subtitles against per-language line-length and reading-speed limits. No account is needed and subtitle files are never uploaded to a server. It suits creators, translators and editors who need a quick fix for one subtitle job without installing a desktop editor.
